Okay there may be many themes of homestuck, but when I was asked what it is in language arts, I said “Don’t turn your back on the body.” As a joke.
Do you know what “Don’t turn your back on the body” means?
It means not to procrastinate, to finish the job, etc. If you don’t do you homework, you could get bad grades. If you neglect your duties you could be punished. If you start on researching, but fall asleep, you might get a bad grade.
Essentially, don’t waste your time.
